Abstract

The aim of this study was to review the clinical outcomes of congenital haemangiomas and lymphangiomas in our unit.

Methods Retrospective cohort study.

Results Between January 2004 and March 2013, over 67,000 infants delivered in Mount Sinai, of which 45 had a diagnosis of haemangioma (n = 23) or lymphangioma (n = 17). Twenty cases were antenatal soft tissue masses, the majority (n = 17) of which were lymphangiomas. These were usually large masses, involving the neck or head (n = 10), thorax (n = 6), abdomen (n = 2) or internal organs (n = 2). Two required antenatal fetal blood sampling and transfusion for anaemia secondary to the mass (one haemangioma, one suspected lymphangioma).

Eighteen women delivered in our unit, at a median gestational age of 38 weeks. Of the eight fetuses with neck masses, three were delivered with EXIT and three by caesarean section (CS) with ENT in attendance. Four women delivered vaginally, two with fetal neck masses. Eight other women delivered by CS, either for obstetric reasons (n = 4) or to minimise trauma to the mass (n = 4). All infants survived to discharge, and twelve were transferred to another paediatric unit for further care.

Conclusions Congenital haemangiomas and lymphangiomas are rare (0.06%). Those diagnosed postnatally were usually small haemangiomas occurring in preterm infants and not causing clinical concern. Antenatal diagnosis were more commonly lymphangiomas and were larger masses requiring multiple attendances to the Fetal Medicine Unit, further high level investigation and delivery within a tertiary level unit to allow for multidisciplinary care.
